IMPROVEMENT IN ROLLING- WIRE.

Specification forming part of Letters Patent No. 138,966, dated May 13, 1873; application filed February 27. 1873.

To all whom it may concern:

Be it known that we, WILLIAM WALTON, of Haughton Dale Mills, Denton, near Manchester, in England, wire-card manufacturer, and JOHN THOMAS FALLOWS, of the same place, sub-manager, have invented certain new and useful Improvements in Machinery for Rolling Wire for Making Wire Cards, and for other purposes; and we hereby declare the following to be a full, clear, and exact description thereof, reference being had to the .annexed drawing forming part of this specification:

Our invention consists, first, in rolling two wires, round or otherwise, in the same groove, or in recesses formed in the circumferences of rollers, in order to produce at one operation two wires of the required section, angle, or other form. Our invention consists, also, in making grooves or recesses of an angular or curved form in the circumference of one or both of the compressing-rollers, the section of the grooves or recesses corresponding to the sh ape of the two angle wires required, so that when the wires are compressed in passing between the rollers, each assumes the shape of half of the groove or recess. These rolled wires are particularly adapted for making wire cards, but they may be used for other purposes.

Description of the Drawing.

In rolling wire according to our improved method we employ a pair of rollers similar to those employed in flattening wire for making the dents of reeds, but instead of making the circumferences of these rollers perfectly plain,

we cause grooves or recesses to be turned or otherwise formed in them, which grooves or recesses are of the required shape and size toconvert the two wires passing between the rollers into two wires having two flat or curved sides and a flat base.

After the wires have been compressed in passing between the rollers, they are wound on reels in the usual manner. The circumferences of the rollers a a are provided with grooves or recesses of the curved shapes required to form the two wires passing between them into the section shown on a magnified scale in Fig.

2-that is to say, each wire has a flat base and two curved sides, or the grooves or recesses in the rollers maybe angular, as shown in Fig. 3, to produce two wires, each with a flat base and with two fiat sides. I

Instead of making curved or angular grooves or recesses in both the rollers (ta, as above described, our invention may be modified by making the grooves or recesses in one roller only, and leaving the other plain, as shown in Fig. 4.

W'res rolled in the manner described may be used for various purposes, but they are particularly suitable for being made into cards for carding cotton and other fibrous substances, as the base of the wire when set in the India-rubber cloth or other material of which the card-clothing is made, forms a good abutment to resist the pressure on the point of the wire and the point and edge of the wire being hardened by the operation of rolling, is found much more durable and does not require to be ground or set so frequently as wire-cards made in the usual manner.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The method of forming two wires simultaneously bypassing them between grooved rolls in the manner described.

In testimony whereof we have hereunto set our hands before two subscribing witnesses.
